Upgrade your towing visibility with the TowMate TM21 21" Wireless Tow Light — an Open Box unit designed to simplify and enhance rear-light signaling on any trailer or towed vehicle. Magnetic mounting means quick, tool-free installation so you can add or remove the light as needed without rewiring your system.

The 21-inch bar delivers bold, unmistakable signals that follow real-world traffic expectations. Amber indicators handle stop, turn, and tail functions, while braking activates a bright red light for immediate recognition. When you signal a turn, the corresponding left or right red strip lights up in sync with the amber indicator, creating a clear, redundant signal pattern that improves safety for you and other drivers.

Signal clarity in all conditions: amber stop/turn/tail indicators paired with a red braking light for rapid distance recognition.
Precise turn signaling: left or right red strip lights illuminate with the matching amber indicator to eliminate confusion at intersections and on winding roads.
Premium finishes for durability and look: choose between Carbon Fiber or Diamond Plate finishes, both hydro dipped for a high-sheen appearance and easier cleaning.
Wireless convenience: includes a transmitter and a charging cord that recharges from your vehicle’s 12V cigarette lighter socket, keeping you ready on the road without invasive wiring.
Open Box value: exceptional functionality at a compelling price point with the same performance you expect from TowMate.

Ideal use cases

Perfect for utility trailers, gooseneck setups, flatbed rigs, and caravans where an extra, independent signal strip enhances visibility. It’s particularly helpful when you need a quick add-on to a secondary hitch, or when you’re coordinating signaling across multiple towed configurations. The magnetized mount makes it easy to reposition for different load types or job sites without permanent mounting.

What makes it stand out

Unlike common taillight add-ons, the TM21 combines wireless control with robust, high-visibility signaling and premium surface finishes. The hydro-dipped carbon fiber or diamond plate look not only elevates aesthetics but also resists grime and is straightforward to wipe clean after a muddy job site. The magnetic attachment, combined with the included transmitter and cigarette-lighter charging option, offers flexible, installer-free operation that can be moved between vehicles or trailers in minutes.

Care and maintenance tips

Wipe the housing with a damp cloth to remove road grime and prevent buildup that could affect visibility. Inspect the magnetic mount regularly to ensure a secure fit, especially after off-road use or rough terrain. Keep the charging cord and transmitter in a dry, accessible place to preserve battery life and ensure ready operation on your next tow.
